Ian Buck helped secure Nvidia's dominance by masterminding CUDA. What he does in light if Jensen Huang's departure is just as vital to the chip giant.

Ian Buck has spent his career building CUDA, Nvidia's most important software. After Nvidia's CEO Jensen Huang's resignation, Buck's role is becoming even more essential to the company's future. Huang's departure brings more attention to his closest collaborators, with Buck at the forefront. Buck has been working alongside Huang since 2004, when he began developing the breakthrough software, Compute Unified Device Architecture (CUDA).

Today, CUDA supports over 900 libraries and artificial intelligence models, each corresponding to an industry using Nvidia technology. CUDA is the platform that allowed Nvidia to achieve nearly 90% market share in AI computing and is crucial for defending the company's moat. As a result, Buck's influence is now more prominent than ever.
